Researchers in over 80 nations are taking part in a project to conduct a decade-long census(统计) of sea life. Scientists presented some of their findings at a recent conference as the project neared its completion.

In deep icy waters under Antarctica, scientists found bulbous tunicates, an underground animal, and many newly-discovered creatures believed to be related to starfish (海星) and other marine(海洋的）creatures.

Elsewhere in the world’s oceans, they have recently discovered many kinds of underwater life forms new to science. It is all part of a research effort called the Census of Marine Life.

“There are about 2,000 scientists worldwide involved,” said Bob Gagosian, President, CEO of the Consortium for Ocean Leadership. Gagosian helps manage the project. “Everywhere they’ve gone they’ve found new things,” he says. “The ocean basically is unexplored from the point of view of marine living things.”

Researchers have placed small markers on hundreds of fish and marine animals to track by satellite their migration(迁移）routes and to discover places where sea life gathers.

According to Ron O’Dor, a senior scientist with the Census of Marine Life, knowledge of life on the ocean floor is especially limited. “90% of all the information we have is from the top hundred meters of the ocean,” O’Dor states.

And he says the sea floor is, on average, at a depth of 4, 000 meters. And so, as some machines dive far below what people have previously seen, scientists are discovering new species of plants, animals and living things.

Since the census project began, more than 5,300 new marine animals have been found. Ocean researchers say they hope to catalogue 230,000 species during the census —which some say is only a small part of all the creatures living in the sea.

1.Why do the researchers place small markers on many marine creatures?

2.From what Ron O’Dor says, we can conclude that ________.

3.What can we learn from the passage?

4.Why does the author write the passage?

Researchers are often interested in how culture changes over time. All cultures go through periods of change and some cultures change faster than others. For example, in the past 10 years, Chinese culture has changed rapidly as western products have become popular. Other countries, such as France, have created rules to prevent their culture from changing too quickly.

Even though cultures change at different paces, the causes of cultural change are quite similar around the world. One of these is technology and medicine. In the United States the invention and development of birth control pills and other measures helped parents to limit the size of their families. As a result, families grew smaller and parents could give more attention to fewer children.　 On the other hand, new technology has also created emotional distance among families.

Cultures also change when they come into contact with other cultures. Immigration, for example, often results in cultural change for both immigrants and the host culture. Immigrants often bring with them different ideas, food, music, language, and manners when they move to a new culture. In Canada, for example, the government has a policy of multiculturalism where immigrants are encouraged to share their background cultures with Canadians while adopting and accepting Canadian culture.

Cultural change can occur due to larger events. For example, economic depression, war, and disaster can endanger societies, which must adapt to these challenges and events. Because of these changes in society, ideas and ways of life also affect the entire culture. For example, during World War II, many American men were sent far off to fight. Consequently, women were suddenly needed to work in the factories. As a result of this change, it is no longer culturally acceptable to believe that they should not have the right to work.

1.In the first paragraph which country has experienced rapid cultural change in the last decade?

A. Canada. B. China. C. France. D. America.

2.What will probably be talked about following the last paragraph?

A. Another reason for cultural change.

B. A discussion of immigration policy in France.

C. Another cultural change caused by World War II.

D. Some examples of highly successful working women.

3.What would be a good title for this passage?

A. Immigration Policy and Culture B. Immigration and Culture

C. New Technology and Family Culture D. Theories of Cultural Change

Hunting

The days of the hunter are almost over in India. This is partly because there is practically nothing left to kill, and partly because some steps have been taken, mainly by banning tiger-shooting, to protect those animals which still survive.

Some people say that Man is naturally a hunter. I disagree with this view. Our earliest forefathers, who at first possessed no weapons, spent their time digging for roots, and were no doubt themselves often hunted by meat-eating animals.

I believe the main reason why the modern hunter kills is that he thinks people will admire his courage in overpowering dangerous animals. Of course, there are some who truly believe that the killing is not really the important thing, and that the chief pleasure lies in the joy of the hunt and the beauties of the wild countryside. There are also those for whom hunting in fact offers a chance to prove themselves and risk death by design; these men go out after dangerous animals like tigers, even if they say they only do it to rid the countryside of a threat. I can respect reasons like these, but they are clearly different from the need to strengthen your high opinion of yourself.

The greatest big-game hunters expressed in their writings something of these finer motives(动机).One of them wrote.

“You must properly respect what you are after and shoot it cleanly and on the animal’s own territory(领地)。You must fix forever in your mind all the wonders of that particular day. This is better than letting him grow a few years older to be attacked and wounded by his own son and eventually eaten, half alive, by other animals, Hunting is not a cruel and senseless killing – not if you respect the thing you kill, not if you kill to enrich your memories, not if you kill to feed your people.”

I can understand such beliefs, and can compare these hunters with those who hunted lions with spears(矛) and bravely caught them by the tail. But this is very different from many tiger—shoots I have seen, in which modern weapons were used. The so—called hunters fired from tall trees or from the backs of trained elephants. Such methods made tigers seem no more dangerous than rabbits.

1.There is no more hunting in India now partly because _________.

A. it is dangerous to hunt there                                                        B. hunting is already out of date

C. hunters want to protect animals                                                   D. there are few animals left to hunt

2.The author thinks modern hunters kill mainly _________.

A .to make the countryside safe                                                       B .to earn people’s admiration

C. to gain power and influence                                                D. to improve their health

3.What do we learn about the big-game hunters?

A They hunt old animals

B. They mistreat(虐待) animals

C .They hunt for food

D. They hunt for money

4.What is the author’s view on the tiger-shoots he has seen?

A .Modern hunters lack the courage to hunt face-to-face

B. Modern hunters should use more advanced weapons

C. Modern hunters like to hunt rabbits instead of tigers

D. Modern hunters should put their safety first
